- set OBJECT targets for osd cpu & gpu libs, and use the obj target for static and dynamic linking - add a new examples_common_obj OBJECT target - replace direct source dependencies to obj target in all examples CMakeLists This change makes it possible to not re-compile the same source files multiple times when they are used in multiple targets. Thanks to jcowles for uncovering the CMake functionality. Note: it seems that multi-process build is working again (gmake -j <x>)
